Giant Scale Night-Flying Midair Crash!

I captured this awesome night flight at Hoverpalooza 2015, and the unfortunate demise of a 100cc PAU Extra 300SP as it was cut in half by a 37% Pilot Yak 54's carbon prop. The Extra got a little too close to the yak's "personal space" and... well, watch the video!
